Thanks for submitting this bug, did you make sure to npm install -g task-master-ai ?

[gauravhp]

Once again it started failing.. this time I again installed "npm install -g task-master-ai" to make sure that is not the issue

yeah, unfortunately, cursor logs aren't very helpful, can you show me your mcp.json config for task-master-ai minus the sensitive info like api token keys of course hehe

@gauravhp were you ever able to get this sorted, taskmaster has very much evolved since!
